It was believed that Twitter.com was hacked and defaced by Hackers connected to Iran because if you’ll access twitter.com, instead of seeing the normal twitter page,  what you’ll see is a black page with this message:

Iranian Cyber Army

THIS SITE HAS BEEN HACKED BY IRANIAN CYBER ARMY

iRANiAN.CYBER.ARMY@GMAIL.COM

U.S.A. Think They Controlling And Managing Internet By Their Access, But THey Don’t, We Control And Manage Internet By Our Power, So Do Not Try To Stimulation Iranian Peoples To….

NOW WHICH COUNTRY IN EMBARGO LIST? IRAN? USA?
WE PUSH THEM IN EMBARGO LIST
Take Care.

But an hour (more or less) Twitter team issued a statement that the DNS of the domain, “twitter.com” was compromised:

Twitter’s DNS records were temporarily compromised tonight but have now been fixed. As some noticed, Twitter.com was redirected for a while but API and platform applications were working. We will update with more information and details once we’ve investigated more fully. (source)

So, what really happened is that when you visit twitter.com, you’ll be redirected to another website.

In other words, Twitter users need not to be worried because it was not the Twitter servers being hacked but just the DNS of the domain.

However, just to make sure that my account would not be compromised, I immediately changed my password.
